    • In embodiments of live television playback optimizations, streaming video content is received (502) for distribution to a client device (104) that is implemented to playback a video content stream for display. The video content stream is associated with a content manifest file (402) that identifies video segments of the video content stream. An input can be received (504) from the client device (104) to switch from the video content stream to a new video content stream, and video segments of the new video content stream are buffered (508). A new content manifest file (408) that correlates to the buffered video segments of the new video content stream is generated (510). The new content manifest file (408) can then be published (512) to the client device (104) to indicate that a minimum of buffered video segments have been buffered for distribution to the client device (104) before the minimum of buffered video segments have been buffered.
    • 在实况电视回放优化的实施例中,流式视频内容被接收(502)以分发给客户端设备(104),客户端设备(104)被实现为回放视频内容流以用于显示。 视频内容流与识别视频内容流的视频片段的内容清单文件(402)相关联。 可以从客户端设备(104)接收(504)输入以从视频内容流切换到新的视频内容流,并且新视频内容流的视频片段被缓冲(508)。 生成与新视频内容流的缓冲的视频片段相关的新内容清单文件(408)(510)。 然后可以向客户端设备(104)发布(512)新的内容清单文件(408),以指示最小缓冲视频段已被缓冲以在最小缓冲视频段(104)之前分发给客户端设备(104) 已被缓冲。
